UNITED STATES SAMUEL W. RUSHMORE, 0] PLAIN FIELD, NEW JERSEY.

RADIATOR Application filed November To all whom it may concem:

Be it known that I, SAMUEL W. RUsH- MORE, a citizen of the United States, and resident of Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Radiator Condensers, of which the following is a specification.

My present invention relates to radiators, particularly radiators for the motor cooling systems of automobiles, trucks and the like particularly when operated as up-flow condensers according to the principles set forth in my prior Patent No.. 1,378,724, granted May 17 1921. In this patent, the cooling water from the motor jacket is short-circuited through the bottom of the radiator and, being insufliciently cooled, gets boiling hot. The space in the bottom of the radiator acts as a separating chamber from which the steam rises 'into the air-cooled passages of the radiator. The condensate returns by gravity, while the boiling water including condensate is returned to the water jacket by the pump.

In applying this system to automobiles and trucks of standard construction, the large size of-the water jacket outlet and its location near the level of the top of the radiator make it awkward to make the downtake a single, pipe of the required size, running from the top of the engine down to the bottom of the radiator. Moreover, the discharge of the steaming water into the bottom of the radiator in a single large stream and from one side only, tends to unduly localize the steam evolution under certain parts of the honeycomb.

In these radiators the chamber below the honeycomb is of limited capacity and in certain cases, particularly radiators of the vertical tube type, particularly when used on trucks where the cooling capacity of the radiating tubes is apt to be overtaxed as by running up long grades on low gear, I find that the increase in the volumes of steam from the water discharged into the lower chamber ofthe; radiator is liable to cause the water to be projected at such high ve-v locity as may be driven up through the tubes by momentum.

To meet these and other difficulties of the situation, my present invention includes dividing the stream from the water jacket and providing two outlet pipes, discharging into the lower separating chamber at two CONDENSER.

points, preferably in opposite directions and from the respective ends thereof. The branch pipes preferably pass downward adjacent to the rear face of the radiator and they may be anchored thereto if desired.

Preferably the single large pipe outlet from the top of the engine jacket is carried forward to the desired point, preferably the vertical planeof the rear face of the radiator, and from there the branch pipes run down each side. For convenience I may provide a casting somewhat like the usual upper inlet casting at the top of the radiator, but blankedoif at theradiator wall so that it serves as a structural anchorage both for the jacket outlet pipe and for its branches.

The branches preferably follow the rear surface of the radiator at or near the marginv of the honeycomb. Entering the bottom of the radiator from each side, they preferably discharge toward each other beneath a perforated bafiie plate which serves the purpose of distributing the steam more evenly across the bottom of the honeycomb and also operates as a splash plate to minimize slopping of the water into the honeycomb.

The above and other features of my invention may be'more fully understood from the following description in connection with the accompanying drawings, in which- Fig. is a rear elevation of a radiator showing one embodiment of my invention.

Fig. 2 is a detail section on the line 2-2, Fig. 1, showing a desirable form of fitting from which the two jacket outlet pipes are branched, and

Fig. 3 is a detail section on the line 3--3, Fig. 1.

The radiator casing 1 and the core or honeycomb 2 may be of any known or desired construction, as for instance, any of those shown in my applications, Serial Numbers 500,581; 500,582; 520,209; or 520,210.

Preferably, however, the casing comprises a bottom chamber or tank 3, a top chamber or tank 4 and the usual filler opening 5 closed by cap 6. For simplicity of illustration, the core is shown as comprising vertical pipes 7, 7, with the usual horizontal radiating fins 8,

8, the pipes being secured with their lower ends opening through the bottom plate 9 and their upper ends opening through'a similar top plate, not shown. Thus the tubes form a through-connection from the lower this. v

a The pipe 11,.bra'nches 12, 13, and the base the hose connection from the top of the water v jacket'in the same way as at present, but the rear end of the casting is blanked ofi", instead of opening through into the top of the radiator. Two branch passages 12, 13, are preferably formed on easy curves so as to afford eas flow paths for the steam or water which, 'un ercertain conditions, will flow through the same at high speed. The branches 12,

'13, will-be of combined cross-section sufficient to take care of the maximum flow of the cooling medium but preferably the flow section of the pipe 11 is even greater than plate 14, are preferably an integr'alcasting and the latter may'besecuredtorthe rea'rface of the radiator by boltsor rivets 15.

. The two branch pipes-16, 17, are secured steam-tight in the'outlets .of-passa'ges 12,13, in any esired way as by screw-threading, brazing or otherwise. Preferably these i branch pipesare close to the rear face of the radiator and extend horizontally tothe respective sides thereof, thence downward along the sides, as at 18, 19, entering the chamber in the bottom of the radiator as at 20, 21, respectively. Inside of-the radiator they are preferably provided with outlet portions 22, 23, shown as adapted to discharge toward'each other.

Above these vnozzles, and preferably at or near the desired working level of the water, but'asubstantial distance below the bottom 9 of the core, is a. bafiie plate 24 provided with perforations 25. The number and size of the perforations is such asto minimize splashing of'the water by side sway of the car or by violent'b'oiling, also to distribute the steam more uniformly across the bottom of the core.
